Tesla Powerwall 3 in Big Creek
The Tesla Powerwall 3 is a 13.5 kWh lithium iron phosphate home battery with a built-in 11.5 kW solar inverter. It stores solar energy for evening use, provides whole-home backup during outages, and integrates with the Tesla app for real-time monitoring. A single Powerwall 3 can back up most Central Valley homes; two units cover high-load households with EV charging.
Big Creek is a remote mountain community in eastern Fresno County, located at approximately 5,000 feet elevation near Huntington Lake, served by ZIP code 93605. The community is a mix of residential homes and vacation properties with excellent solar exposure — the mountain elevation and clear air deliver strong solar irradiance, and cooler temperatures significantly improve panel efficiency compared to valley floor installations. PSPS outages are frequent and can be prolonged during fire weather season, sometimes lasting 3–5 days. For Big Creek homeowners, battery backup is not optional — it's a practical necessity for maintaining power to critical loads during extended outages.
Valley floor cities like Fresno and Clovis have lower PSPS risk but high summer electricity rates. Powerwall 3 maximizes your NEM 3.0 solar value by storing midday production for evening use — avoiding PG&E's peak rates from 4–9 PM.
Why Powerwall Makes Sense in Big Creek
- PG&E outages during summer heat events and PSPS events
- High evening electricity bills under NEM 3.0 (store solar, use at night)
- Eliminating grid dependence for households with high AC loads
- EV charging from solar surplus rather than grid power
Who It Is Right For in Big Creek
- Homeowners with existing solar who want battery backup
- New solar + battery installations (Powerwall 3 includes the inverter)
- Households with medical equipment requiring outage protection
- EV owners who want to charge from stored solar overnight
- Homes in PSPS-risk areas (foothills, rural Fresno/Madera/Tulare counties)

Tesla Powerwall 3 Installation Details for Big Creek
System Sizing
One Powerwall 3 (13.5 kWh) covers essential loads for 12–24 hours for most Central Valley homes. Two units are recommended for whole-home backup including AC, or for households with EV charging. Robbins Energy sizes battery systems based on your actual PG&E usage data.
Solar Integration
Powerwall 3 includes a built-in solar inverter — for new installations, no separate string inverter is needed. For retrofits onto existing solar systems, a Gateway 2 or Backup Switch is required. Robbins Energy handles both new installs and retrofits.
Backup Power
Powerwall 3 supports whole-home backup — not just a critical loads panel. During a PG&E outage, your home transitions to battery power in under 20 milliseconds. Storm Watch mode monitors PG&E outage alerts and pre-charges the battery before a PSPS event.
Panel & Electrical
Powerwall 3 installation requires a 200-amp main panel. Homes with 100-amp service (common in older Fresno, Madera, and Tulare County neighborhoods) need a panel upgrade first. Robbins Energy performs panel upgrades as part of the installation. Valley floor cities typically have flat terrain with excellent south-facing roof exposure. Most homes have unobstructed solar access. Older neighborhoods may have 100-amp panels requiring upgrade.
Permitting in Big Creek
Permits issued by: Fresno County Building Department. Battery storage installations require a building permit and PG&E interconnection approval in all Central Valley jurisdictions. Permit timelines vary: Fresno and Clovis typically 2–3 weeks; rural county jurisdictions 3–5 weeks. Robbins Energy handles all permitting. PG&E NEM 3.0 interconnection required. Robbins Energy handles the full interconnection application, which typically takes 4–8 weeks for approval after permit issuance.
Roof & Site Notes
Flat valley terrain means most rooftops have near-ideal solar orientation. Minimal shading from trees or neighboring structures in most neighborhoods. Remote. Many older homes and vacation properties.

Is battery storage worth it in Big Creek under PG&E NEM 3.0?
Under PG&E NEM 3.0, battery storage is essential to maximize the value of your solar investment. Export rates are low; storing solar for evening use avoids buying power at peak rates (4–9 PM). In Big Creek, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.
What is the outage and PSPS risk in Big Creek?
This community is in a high-priority PSPS zone. PG&E regularly shuts off power here during high-wind fire weather events — sometimes for 2–5 days at a time. Battery storage with Storm Watch or equivalent pre-charge capability is strongly recommended for all households. Very high. Frequent and prolonged PSPS events. Battery backup essential.
What is the difference between Powerwall 3 and Powerwall 2?
Powerwall 3 (released 2024) includes a built-in 11.5 kW solar inverter — for new solar installations, no separate string inverter is needed. Powerwall 2 required a separate solar inverter. Powerwall 3 also has higher continuous power output (11.5 kW vs 5 kW) and supports whole-home backup more effectively. Robbins Energy installs Powerwall 3 for new systems and can retrofit Powerwall 2 onto existing solar.
Can Powerwall 3 power my whole house during an outage?
Yes — Powerwall 3 is designed for whole-home backup, not just critical loads. A single unit (13.5 kWh) can power most Central Valley homes for 12–24 hours depending on AC usage. Two units cover high-load households with EV charging. During a PG&E outage, your home transitions to battery power in under 20 milliseconds — most appliances don't even notice the switch.
Does Powerwall 3 qualify for the federal tax credit?
Battery storage systems installed with solar may qualify for the federal Investment Tax Credit (ITC). Tax credit eligibility depends on your individual tax situation. Robbins Energy recommends consulting a tax professional for guidance specific to your circumstances. We do not provide tax advice.
